Field Installation Guidelines
Verify that the incoming AC supply voltage matches the 120 / 240 V AC rating before energizing the power supply unit.
Secure all terminal block connections tightly to maintain low-resistance current paths and prevent localized heating.
Ensure proper chassis and ground terminal bonding to satisfy surge voltage protection limits and electrical safety standards.
Maintain adequate spatial clearance around the enclosure housing to allow unobstructed convective cooling and heat dissipation.
